Magnitude 5.5 Earthquake on the western shore of Lake Kivu.

The United States Geological Survey Recorded a Magnitude 5.5. Earthquake at a depth of 10 km beneath the western shore of Lake Kivu, which forms the border between Rwanda to the east and the Democratic Republic of Congo to the west, slightly before 3.30 am local time (slightly before 1.30 am GMT) on Friday 7 August 2015. There are no reports of any damage or casualties associated with this event, but it was felt as far away as Kigali in Rwanda and Bujumbura in Burundi.

Lake Kivu lies on the western branch of the East African Rift, which is slowly splitting the African Plate in two along a line from the Red Sea through Ethiopia, and which includes the great lakes and volcanoes of east-central Africa. This has the potential to open into a new ocean over the next few tens of millions of years, splitting Africa into two new, smaller, continents; Nubia to the west and Somalia to the east. This is not a smooth process as the rocks naturally stick together, breaking apart only when the pressure builds up sufficiently, producing infrequent, but sometimes quite large, Earthquakes in the process.

Witness accounts of Earthquakes can help geologists to understand these events, and the structures that cause them. The international non-profit organization Earthquake Report is interested in hearing from people who may have felt this event; if you felt this quake then you can report it to Earthquake Report here.
